IVCAD MT930C offers a modern and efficient methodology for load-pull measurements. Low-loss couplers, inserted between the tuners and DUT, are connected to a VNA to allow real-time measurement of a and b-waves at the DUT reference plane, enabling vector information not normally made available with traditional setups.
IVCAD measures the real load impedance presented to the DUT without prior assumptions of tuner characterization, positioning, or losses. Extremely accurate transistor’s input impedance derived from the a-and b-waves results in properly-defined true delivered input power, power added efficiency, and true power gain measurements. Output powers, at fundamental and harmonics, are made available along with multi-tone carrier and intermodulation powers.
